Interface dynamic behavior between individual carbon nanotubes (CNTs) and tungsten (W) electrodes is observed directly at a nearly atomic resolution. The W tip‐end absorbs the source CNT atoms, which then penetrate deep into its body, form a carbide, and finally precipitate as freshly formed graphitic tubular shells encapsulating the electrode. CNT wall‐thickness shaping via stepwise absorption of...
We directly observed the Joule-heating-induced decomposition of multiwalled BN nanotubes using a transmission electron microscope equipped with a scanning tunneling microscope unit. The decomposition temperature is found to be dependent on an applied electrical field. We propose a model that due to the partially ionic nature of the B–N bond, the decomposition energy is both temperature- and electrical...
The electrical and mechanical properties of the same hybrid carbon nanotube before and after removal of the core Ga-doped ZnS semiconductor filling have been analysed inside a transmission electron microscope (TEM) using a conductive atomic force microscope – TEM system. It is found that the encapsulated material can substantially change the mechanical response of the turbostratic carbon tube container...
